Siab zog steel phaj Q620E
Kev siv tus qauv ntawm Q620E qis alloy steel phaj yog GB / T tshwj xeeb kev mob. Qhov "Q" nyob rau qib Q620E sawv cev rau lub zog ntawm cov hlau, "620" txhais tau hais tias lub zog ntawm cov khoom muaj nqis tsis tsawg dua 620MPa, thiab "E" sawv cev rau qib zoo.
Q620E siab zog steel phaj muaj qhov kub thiab txias toughness thiab tuaj yeem tswj kev ua haujlwm ruaj khov ntawm qhov kub thiab txias. Ntxiv rau qhov muaj zog thiab siab tawv, Q620E siab zog alloy steel phaj kuj muaj siab hnav tsis kam, cuam tshuam tsis kam, corrosion kuj, qaug zog thiab ua haujlwm yooj yim, ua tau raws li kev siv raws li ntau yam kev ua haujlwm nyuaj.
